Diamond Bi-Fold Doors

Excellent door. Weather Tite and quick opening. Long running company with a well proven concept.

Outstanding product. Exceptional service. The door fit well, is finished well, and operates flawlessly.

They were informative and helpful right from the beginning from ordering to delivery. I wanted my door before winter and they even changed their logistics to accommodate.

I did the install myself and the directions are easy to follow, very thorough and well thought out (it's still quite a bit of grunt work). I had one hiccup and the service/help was first rate. Great company to deal with!

Had a 40’x16.6’ insulated diamond door installed this summer. We absolutely looove it. We also did the optional auto lock system that allows the door to open and close with the push of a button. It’s amazing, I have a couple remotes, one for the plane and one for the quad. I can fly over hit the button and the doors open ready for me to taxi right in. It’s a real time/life saver in the work I do.
The door itself is really well built and seals nice in winter. No gaps for cold air or wind to whistle through.
It’s made the building way more usable and and user friendly versus the four panel sliding doors I had before.

received door 42 wide by 12 high. had factory support all the way .borrowed a fork lift and hung it by myself. called welder and hinges welded to structure. all in all fabrication quality is professional and strong. I would definitely recommend this fabricator.

We have purchased many doors over the years from Diamond Doors and they always have great service and great products. Thanks for always taking care of us and our customers!
